WHO: Victoria Vaughn Holsted (a resident of Franklin, TN) and her
sister, Valerie Vaughn (a resident of Birmingham, AL), were in Los
Angeles for a brief winter vacation. On January 27, 2009, they boarded
Southwest Airlines Flight 1705 at Los Angeles International Airport,
destined for home. The plane was a Boeing 737-300 jet aircraft and was
scheduled to stop in Nashville, TN, Birmingham, AL and Baltimore, MD.

About one-hour into the flight they, along with the other passengers,
began to experience oxygen deprivation, among other problems. Alerted to
the problem, the pilot then engaged the engines at full thrust and
entered a steep ascent. As this occurred, super heated air began to
surge out of the ventilation system and onto the passengers. Also
present was the appearance of a mist. The plane made an emergency
landing in Albuquerque, NM. The sisters and other passengers then took
another flight that went on to Nashville and then Birmingham.

During and after Southwest Airlines Flight 1705, both Victoria and
Valerie experienced such symptoms as extreme pressure in their heads,
nasal passages and ears which did not go away. These symptoms were
followed by serious physical and mental ailments, including tremors,
memory loss, motor skill deficiencies, blurred vision, numbness and
tingling in their extremities, among others.

Despite repeated requests, Southwest Airlines gave the sisters the
runaround when they called the airline with questions as to what they
were exposed to on Flight 1705 so that their doctors would know how to
best care for them; and calls that they made to the FAA (Federal
Aviation Administration) offered no pertinent information. Through this
Petition, they seek to preserve and obtain information that is vital to
their medical treatment. Victoria Vaughn Holsted and Valerie Vaughn,
Petitioners, vs. Southwest Airlines Co., Expected Adverse Party,
Case No. BS120400.
